Hey, this
^^^^^^^^^^^^^^^^^^^^^^
it's a way to get the current module, right? Nice trick, I didn't think of this.
Its limitation is it won't work outside the 'main() {}' module.
You can get the parent of an alias. The following template finds all overloads
of a given symbol:
template ID(T...){alias T ID;}
template getOverloads(alias f){
enum fname = f.stringof[0..f.stringof.indexOf("(")];
alias ID!(__traits(getOverloads, __traits(parent, f), fname)) getOverloads;
}
I think this should go into std.traits, as soon as it works. (DMD is buggy when
it comes to taking the .stringof of a function. It misinterprets it as a
property function call in some cases but not in others. Messy.)
Yeah, your version does not work with my old GDC either (stringof returns
really weird
things here...); this one works:
template ID(T...) { alias T ID; }
template getOverloads(alias F) {
alias ID!(__traits(getOverloads, __traits(parent, F),
__traits(identifier, F)))
Nice one.
getOverloads;
}
and looks obvious enough; it would be nice to get rid of that extra ID step,
though.
